SSL & pymqi: I got an email about SSL and
Les Smithson's
pymqi this morning. I added some code to pymqi
a couple of years ago, and it turns out that my code
needs further extension to enable SSL support. I don't
have time to do this work myself. But I thought I'd
better blog my recommmendations so they're in the Google
cache for anyone else who runs into this issue.

First off, you need IBM's SSL MQ sample. You can
find this by Googling for ssl mq mc6c. It
has some example code: amqscnxc.c, which shows
the SSL config info being put into a struct that's
passed to MQCONNX. The struct is an MQCNO which
pymqi 4c doesn't implement. MQCNO holds a ptr to an MQCD,
which I added to an earlier version of pymqi.

So to enable SSL configuration in pymqi, you must
implement a Python class for the MQCNO struct, and allow
it to be passed into QueueManager.connectWithOptions, and
then into MQCONNX. The following changes to pymqi will be
needed...

Add class cno(MQOpts) to pymqi.py. Use my cd class
as a template, but follow the structure of MQCNO.

Change QueueManager.connectWithOptions() to add an
extra param: an instance of your new cno class.

Change pymqe_MQCONNX() in pymqe.c to extract the
new param you added in 2, and pass it through to
MQCONNX.
